SHARPENING DEVICE.

Speccaton of Letters Patent.

Patented Oct. 10, 1905.

Application tiled February 6, 1905. Serial No. 244,503.

Be it known that I, CHARLEs MARTIN MAL- l Loin', a citizen of the United States, residing at Chattanooga, in the county of Hamilton and i State of Tennessee, have invented a new and useful Sharpening Device, of which the following is a specification.

This invention relates to sharpening devices for edge-tools, and has for its object to embody the same in the natui'e of a hone and to provide cei'tain new and useful improvements whereby the life of the active surface of the hone is materially prolonged and the handling of the device is facilitated.

\Vith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be herein after more fully desci'ibed, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, propoi'- tion, size, and minor details may be made within the scope of the claims without departng from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure l is l a perspective view of a hone embodying' the features of the present invention. Fig. 2 is a cross-sectional view thereof. Fig. is a longitudinal sectional view on the line 3 3 of Eig. 2. Fig. 4 is a detail view of one of the end plates of the hone.

Like characters of reference designate corresponding' parts in each and every ligure of the drawings.

ln carrying out the present invention there is provided a body or base l, preferablyY in the natui'e of an oblong block of wood to render the same both light, durable, and inexpensive. The upper surface of this body is flat throughout its entire .length and width, and the opposite longitudinal edges thereof are provided with corresponding longitudinal grooves or channels Q, extending entirely throughout the length of the body. The edge portions of the body between the grooves or channels and the top are rounded or beveled, as clearly indicated in Fig. 2.

The active surface of the present hone con sists of a single piece of relatively soft sheet metal 3, which is iitted flat upon the top of the base or body and is pressed around the edges of the body and into the grooves oi' channels 2 with suflicient force to retain the y plate upon the base without other fastening means.

lVhile it is not absolutely essential to the present invention, it is proposed to guard against endwise play of the metal part 3 by means of metal end plates 4 and 5, which are substantial duplicates in form and are shaped to lit the respective ends of the base, to which they are secured by means of suitable fastenings 6. The opposite upright edges of each plate are cleft to produce coi'responding flaps or tongues 7, which are bent into the ends of the grooves o1' channels 2 and around the end portions of the metal sheet 3, which are forced into said grooves, thereby to prevent endwise looseness of said metal sheet. The upper edges of the end plates 5 should lie within the external surface of the metal part 3, so as to avoid projections in the path of an edgetool being' worked back and forth across the hone.

It will hei'e be explained that the outer sui'- face of the metal part is smooth and polished, and it is proposed to apply a gi'anularabi'asive material to the metal pait when it is desired to sharpen a tool. In order that such abrasive material may always be at hand, there is provided a receptacle S to contain gi'anular emery, carborundum, or other suitable material, said receptacle being provided with a perforate shaker-head 9 to facilitate the distribution of the granular material upon the pla-te 3. This i'eceptacle is carried within a seat or socket l0, foi'med longitudinally in the body l and opening through one end thereof, one of the end plates (shown in the drawings as plate 5) being provided with an opening 1l to give access to the socket 10. A suitable pivotal closure 12 is mounted upon the plate 5, as indicated at 13, and is capable of swinging' across the opening' ll to close the same, there being a lip 14: cleft from the plate and sprung outwardly therefrom to form a keeper between which and the plate the free end of the closure l2 is designed to lit, so as to hold the closure in its closed position. The closure is provided with a longitudinally-pressed-out rib portion l5, which stiti'ens the closui'e and constitutes a linger-piece for convenience in swinging the closure open.

In using the hone the closure l2 is open, the receptacle S is removed, and a suitable quantity of granular abrasive material is shaken upon the metallic surface 3, after which the edge tool to be sharpened is woi'ked back and forth across the metallic surface of the hone in the usual manner.

From the foregoing description it will be IOO IIO

understood that the device of the present invention is exceedingly simple, inexpensive, and durable and is embodied in such form so as to enable the convenient handling thereof. The metallic face 3 is secured to the base member in a simple and etfective manner, and the receptacle for containing the abrasive material is removably carried Within the base, and therefore always conveniently at hand for immediate use.

Having fully described the invention, What is claimed isl. A sharpening device for edge-tools comprising a base having opposite longitudinal edge grooves, a metallic plate fitted snugly to the ltop of the base and pressed snugly around the edges thereof into the grooves, and plates secured to the ends of the base and provided With tongues bent into the ends of the grooves vof the base and across the metal plate to prevent endwise looseness thereof.

and a closure for the socket carried by the said end plate.

1n testimony that I claim the foregoing as my own I have hereto aiiixed my signature in the presence of two Witnesses.
